• Provides bidirectional data transmission with direction control
• Features 3-state outputs for easy system interfacing
• Designed for low power consumption and high noise immunity

Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications

Procurement Notes

Verify the specific suffix 'GRG4' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the exact logic family variant required for your design. Cross-reference the manufacturer's official documentation for any recent lifecycle changes or recommended replacements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring 16-bit data transfer at voltages between 1.65 V and 3.6 V. It is suitable for applications needing bidirectional bus arbitration with minimal propagation delay. Consider the TSSOP-48 package constraints for PCB layout. Verify input/output voltage levels match the connected devices to ensure signal integrity across the operating temperature range.

Part Context

This device belongs to the Texas Instruments LVCHR series of bus transceivers. It shares functional similarities with other 16-bit transceivers like the LVC and LVTH families but offers specific electrical characteristics tailored for low-voltage operations. The 'H' designation typically indicates specific drive strength or speed optimizations within the broader logic family portfolio.

Replacement Considerations

Check for direct substitutes such as SN74LVCHR16245ADGGR or SN74LVCHR16245ADLR if pin compatibility is required. Verify that alternative packages maintain the same electrical specifications and thermal performance. Consult the manufacturer's substitution guide for validated cross-references.
